The move happens less than 24 hours after Weaver was forced to leave the game against the New York Yankees.
Paul Severino of MLB Network tweeted the news on Tuesday:
#Angels have placed Jered Weaver on the 15-day DL with lower back strain with spasms.

The Angels have called up Garrett Richards from Triple-A Salt Lake in the corresponding move, and he will likely start in place of Weaver.
Initially, many felt the injury was to his leg. But after the game, trainers hinted that it involved his back. Now we know he has suffered a strain and is experiencing spasms in his lower back.
The Angels will have a difficult time filling the void left by Weaver, especially considering that Roy Oswalt agreed to terms with the Rangers earlier on Tuesday, according to Ken Rosenthal.
They were just beginning to make waves in the AL West, as they are winners of seven straight games. It will be interesting to see if they are able to continue their hot streak as they try to keep things close with the division-leading Rangers.
Weaver brought a 6-1 record and a 2.61 ERA into Monday's game before his departure. There is no timetable on his return at this moment.
