Per T.R. Sullivan, Texas Rangers outfielder Josh Hamilton, who was pulled in today's game after injuring his shoulder on a slide into home, has a "dull pain" in the shoulder, although there's no fracture and the team doesn't think there's a separation or dislocation.
Sullivan does suggest that the disabled list is a possibility. The Rangers are already working with a short bench, due to the team's decision to roll with an eight man bullpen (thus increasingly the likelihood that someone besides Neftali Feliz would pitch in the bottom of the ninth in a tie game with the bases loaded), so if Hamilton is going to miss more than just tomorrow's game (and Hamilton was already slated to get tomorrow off), it could necessitate a move, even if Hamilton doesn't go on the d.l.
Craig Gentry and Chris Davis seem to be the likely candidates to be recalled, should the Rangers make a roster move. If Hamilton doesn't go to the disabled list, you could see either Mark Lowe optioned to AAA, or Dave Bush put on waivers after he makes his spot start tomorrow. Bush was put on the 25 man roster to be the team's long reliever, and has yet to appear in a game.
