To deal with Barajas' absence, the Pirates optioned first baseman Matt Hague to Triple-A Indianapolis on Tuesday and called up catcher Eric Fryer. To make room for Fryer on the 40-man roster, left-hander Daniel Moskos was designated for assignment. The organization also optioned left-handed reliever Doug Slaten when they activated infielder Drew Sutton, who was claimed off waivers from the Rays on Sunday.
"We don't think he'll be a DL candidate," Hurdle said. "But we do have a bone contusion to deal with; sometimes they respond sooner than later. But we're in a position now where every game matters, and I don't think it would be fair to Rod or to our club to carry one catcher through this period."
After tests on his knee came back clear, Barajas said, "[It's] just a matter of time -- having it heal and see how we go day by day."
He said the knee felt a little better on Tuesday than it did after Monday night's game.
"[There's] still some soreness there, especially if I sit around for a while, and not moving around it definitely tightens up a little bit," said Barajas, who is hitting .224 with seven home runs and 18 RBIs. "It's a lot better than I thought it would be, so that's a good sign."
Barajas sustained the injury on a play at the plate in the bottom of the first inning of Monday's game, when Jimmy Rollins scored on a single by right fielder Hunter Pence. Though shaken up, Barajas stayed in for the rest of the frame, but Mike McKenry pinch-hit for him in the second and remained in the game at catcher.
"I went to try to block the plate. and [Rollins] slid into the bottom of my shoe and kind of jarred my foot back," Barajas said. "So the bones basically just kind of hit each other, and that's where you get the bone bruise."
Barajas has no problem squatting, but the injury would affect his explosiveness in certain situations, such as trying to block a ball or jumping up to throw a ball to second base.
McKenry started Tuesday's game against the Phillies, with Fryer backing him up.
"This eliminates the burden of responsibility for a short period of time, where Rod can focus on getting well and we have Eric available to catch," Hurdle said.
