The team said Trout received a cortisone injection Monday morning and remains day-to-day.
Trout, who turns 27 Tuesday, hasn't played since injuring his wrist while sliding on a steal attempt last Wednesday at Tampa Bay.
The Angels beat the visiting Detroit Tigers 6-2 on Monday in the opener of a three-game series. Eric Young Jr., who has filled in for Trout at center field, homered in the fifth inning and finished 1-for-2 with two RBIs.
Trout had expected to be back earlier, but his wrist has not responded to treatment as hoped. X-rays and an MRI revealed inflammation.
Following Saturday's game, Trout said that it's been "frustrating. You don't want to be sitting on the bench watching your team out there."
Trout is batting .309 with 30 home runs in 109 games.
