SARASOTA, Fla. -- Blue Jays outfielder Corey Patterson will follow doctor's orders and miss the start of the regular season for precautionary reasons.

Patterson was hit on the back of the helmet by a Josh Bard fastball during Friday night's game against the Red Sox.

The 31-year-old will begin the season on the disabled list, but it's currently unclear whether that will be the new seven-day DL or the 15-day DL.

The seven-day DL, which was announced Tuesday, is designed for players who are suffering from concussions. Blue Jays manager John Farrell was aware that new procedure was being discussed, but since it was released Tuesday afternoon he was unsure of whether it would be applicable to Patterson.

"I don't have the particulars or defined policy with that, so whether or not that would come into play with Patterson or not remains to be seen," Farrell said.

Patterson underwent a CT scan Friday night and passed a series of concussion-impact tests in the following days. Farrell originally thought that Patterson would be available to play in Tuesday's game against the Orioles, but his doctor recommended more rest to ensure that there were no lingering effects.

"The doctor that has examined him has recommended seven days from the incident," Farrell said prior to the game.

That means if there are no complications for the remainder of the week, Patterson could appear in a Minor League game on Friday. His stint on the disabled list can be backdated to March 25.

Patterson signed a Minor League contract with an invite to Spring Training, but was recently added to the Blue Jays 40-man roster and was expected to make the club as a fourth outfielder. He is a career .253 hitter with 112 home runs and 205 stolen bases over 11 seasons.

Utilityman Mike McCoy will back up center fielder Rajai Davis in Patterson's absence.

Blue Jays acquire utilityman Nix from Indians

SARASOTA, Fla. -- The Blue Jays acquired utilityman Jayson Nix from the Cleveland Indians for cash on Tuesday afternoon.

Nix appeared in 12 games this spring for Cleveland and hit .176 with one home run and two RBIs. His best position is second base but Blue Jays manager John Farrell is confident that he can be used all over the field.

"Right-handed hitter that has versatility," Farrell said when describing Nix. "Second baseman, third baseman, can play the corner outfield positions as well.

"We feel like he will fit very well into our clubhouse, from all the reports on the individual, and we're looking forward to getting him into camp."

Nix is out of options in his contract and Farrell confirmed that the native of Dallas would be on the club's Opening Day roster. The 28-year-old has spent three seasons in the Major Leagues with three different organizations.

He owns a career .215 batting average but does have 26 home runs in 642 career at-bats. Nix became available when he was informed earlier this week that he would not be making the Indians roster.

The Blue Jays placed left-hander Jesse Carlson on the 60-day disabled list to make room for Nix. Carlson appeared in just one game this spring because of a left shoulder strain.

Carlson visited Dr. James Andrews on March 23 to have the injury examined but there was no structural damage found. He received a platelet rich plasma injection into his left bicep to help deal with inflammation, and at the time Farrell said that he did not have a set schedule for his return.

Snider leaves game with tightness in hip

SARASOTA, Fla. -- Blue Jays outfielder Travis Snider was removed from Tuesday afternoon's game against the Orioles with tightness in his left hip.

Snider suffered the minor injury while sliding into second base in the top of the second inning. The 23-year-old said that the move was precautionary and he expects to be ready for Opening Day on Friday.

"It was just tightening up, and I could do what I've done in the past, play through it, but that's when you really expose yourself to injury," Snider said.

Snider will be re-evaluated on Wednesday and could miss the final spring game of the year against the Rays.

The native of Seattle is hitting .333 with one home run and seven RBIs in 16 Grapefruit League games.

Worth noting

Right-handers Brandon Morrow and Frank Francisco will travel north with the Blue Jays on Wednesday night and are expected to throw a bullpen session the following day. Both pitchers will start the season on the 15-day disabled list ... Infielder John McDonald said that he is fully recovered from soreness in his right forearm and is ready for the start of the regular season. McDonald struck out in his only plate appearance during Tuesday's game against the Orioles.
