TORONTO -- Infielder Jayson Nix was placed on the 15-day disabled list Saturday with a left knee bruise.

The four-year veteran suffered the injury Friday night against the Rays when he collided with Sean Rodriguez at second base while trying to turn a double play. Rodriguez slid hard into the bag and made contact with Nix's knee, buckling his left leg under him.

The former first-round pick had X-rays on his leg after the game Friday, which came back negative. An MRI Saturday morning also found no structural damage to the ligaments in the knee.

Nix will fly down to Florida Sunday to begin rehabilitation. The 28-year-old will stay off the leg for at least seven days before beginning to resume baseball activities.

The Blue Jays did not want Nix to travel with the team on its 10-game road trip through Texas, New York and Tampa Bay because air travel can affect the injury.

"It's important to keep him off the leg as much as we can over the next several days," manager John Farrell said. "We feel like we somewhat dodged a bullet, but unfortunately we're going to miss him for the two weeks."

Utility player Mike McCoy was recalled from Triple-A Las Vegas to take Nix's spot in the lineup, and started Saturday afternoon at second base, batting ninth.

Encarnacion scratched due to sore wrist

TORONTO -- Edwin Encarnacion was a late scratch for Saturday afternoon's game against Tampa Bay with a sore left wrist.

The 28-year-old third baseman has battled ailments in his left wrist for the past two years. He had offseason surgery following the 2009 season to remove a bone spur from the wrist, and spent 15 days on the disabled list last season with a sprain in the same area.

Encarnacion was scheduled to start at third base and bat cleanup against Rays No. 1 starter David Price. John McDonald took over at third in place of Encarnacion, with Mike McCoy moving to second and Travis Snider getting the start in left field.

Blue Jays manager John Farrell said before making the change that with the rash of Blue Jays injuries on the infield, he would be giving Encarnacion more starts at third base.

"The way Edwin is swinging the bat, he's going to find himself in the lineup every day," Farrell said. "Edwin is going to get some time at third, and he's going to also be in the DH role as well."

Encarnacion has been one of Toronto's best hitters of late, batting .382 with 13 hits and six doubles over his last eight games.

Farrell also said he wants to get outfielder Juan Rivera more time in the lineup, as the 32-year-old attempts to hit his way out of an early season slump. Farrell chalked up most of Rivera's struggles to not finding his timing through the zone.

"We're trying to get Juan going a little bit," Farrell said. "His work ethic, his approach and his attitude has been very consistent. But you can see inside there's some frustration going on."

Hill working out, decision expected Sunday

TORONTO -- Injured Blue Jays second baseman Aaron Hill worked out Friday and Saturday, and the team will make a decision on whether to place Hill on the 15-day disabled list Sunday.

"He's actually going to jog today. He swung in the cage yesterday a little bit. He's feeling some improvement," Farrell told reporters Saturday morning. "By tomorrow we'll have some definitive answer on his status."

Hill strained his right hamstring while stealing a base in a 6-5 win over the Yankees on April 19. If the club did put Hill on the DL, they could make the move retroactive to April 20, since he hasn't played since he suffered the injury.

Hill's status may inevitably affect the starting rotation. The Blue Jays have yet to name a starter for Tuesday's game against Texas in place of Brett Cecil, who was optioned to Triple-A Las Vegas earlier this week.

If the team intends on recalling a player from Triple-A to make the start, they would either have to option a player or place someone on the DL, with Hill the most likely candidate.

Right-hander Jesse Litsch started for Las Vegas on Friday night, but was pulled from the game after just three innings and 44 pitches. Farrell indicated Saturday that he would be comfortable with starting Litsch Tuesday on short rest.

If Hill is not placed on the DL, right-hander Carlos Villanueva, currently in the Blue Jays bullpen, could make Tuesday's start. The 27-year-old started for the Brewers last season, but hasn't thrown more than 42 pitches in an outing in 2011.

"We've got a lot of moving parts," Farrell said. "But the fact that Carlos has the ability to step in and start and at least get us five innings is good."
