According the Boston.com's Extra Bases blog, Jacoby Ellsbury's collision with Reid Brignac, the Rays' shortstop has resulted in a shoulder subluxation (a partial separation) and will be out 6-8 weeks.
Brignac apologized profusely, and it was obviously an accident, so I don't think there will be any hard feelings. Unfortunately, all the apologies in the world won't allow Che Hsuan-Lin to replace Ellsbury's production while Golden Boy rehabs.
SoxProspects.com rates him well with "Plus speed. Ability to steal 20-25 bases in the big leagues. Well-above average defender. Possesses outstanding defensive instincts. Seems to get a head start on balls off the bat. Covers excellent ground from gap-to-gap. Plus-plus arm, with improving accuracy."
Sadly, Lin will probably be unable to live up to Bill James' projections for Ellsbury: .304 BA, .362 OBP, .476 SLG. If Ells is back in exactly eight weeks, we should see him for the beginning of interleague play in Washington, DC on Friday, June 8th.
Can the Red Sox do it without him until then? They've already lost their closer, Andrew Bailey, until sometime around the All Star Break, and the loss of the runner-up for the 2012 MVP Award can't be overlooked. Personally, I think they'll be able to hang in - so long as the pitching staff can hold things together.
