Twins catcher Joe Mauer remains day-to-day with a bruised right quadriceps muscle, Twins general manager Terry Ryan said Monday.

Mauer got kneed in the quad by Milwaukee's Rickie Weeks on a slide into home plate Sunday.

"It's not anything we need to worry about," Ryan said. "There's still some tightness, but I think he'll be OK in the near future."

Twins closer Matt Capps was unavailable to pitch on Saturday and Sunday because of a sore shoulder.

"Capps is fine," Ryan said. "They're both day-to-day."

Ryan said he has no concerns about either player needing to go on the disabled list. The Twins are off Monday and flying to Pittsburgh, where they'll begin a three-game series with the Pirates on Tuesday.
