With catchers Josh Paul (back) and Dioner Navarro (wrist) both banged up, the Rays reached down to Triple-A Durham's championship series roster again Tuesday and called up veteran Raul Casanova.

To re-add Casanova to the 40-man roster, the Rays designated for assignment RHP Tim Corcoran, who had been pitching for Double-A Montgomery.

Casanova was up with the Rays earlier this season. Navarro is starting tonight in Boston.

Paul said his lower back spasms are "getting better" and hopes to be able to catch RHP Edwin Jackson as usual tomorrow.

"My back was in a knot," Paul said of missing a scheduled start to catch LHP Scott Kazmir Monday. "I think it will be OK. I just need a couple of days to loosen it up."

Casanova's flight from Durham was delayed this afternoon, but he's stil expected to be in uniform tonight.

As for Corcoran, who threw three scoreless relief innings in the Biscuits' Southern League division series win, he was told by Montgomery manager Billy Gardner he can be back for Thursday's SL finals Game 2 if he clears waivers.

"They asked if I would sign back to play in the playoffs," Corcoran told the Montgomery Advertiser. "Of course, that's what I'm going to do. I'm not going to sit there and wait 10 days and let the season be over with."

UPDATE (4:49 p.m.): The rain just let up here at Fenway and the skies appear to be clearing. Players from both teams are assembling in the outfield.
