Arroyo (hamstring) could be activated off the 10-day injured list at some point this weekend, Chris Cotillo of MassLive.com reports.
Arroyo kicked off a rehab assignment at Triple-A Worcester on Tuesday, going 0-for-2 while starting at second base. He was given the day off Wednesday and is scheduled to play second base again Thursday. Barring any setbacks, he could rejoin the club for the weekend series against the Rangers. Red Sox manager Alex Cora mentioned Arroyo working out at first base, but he's not expected to play first base in game action just yet.
