Angels manager Mike Scioscia said Kevin Jepsen (triceps) is "close" to rejoining the bullpen.
Jepsen, who has been out since mid-April with a triceps ailment, will make a third rehab appearance this week, but it sounds like it could be his final one. He'll return to middle relief for the Halos.
Will Middlebrooks left Thursday's game against the Indians after the fourth inning with lower back spasms.

Middlebrooks struck out the inning before, but it's not clear if he tweaked something during that at-bat or earlier. It's not clear at this point how serious the ailment is. The Red Sox should provide an update after the game.
