Update: Wes Welker is out indefinitely after being diagnosed with his third concussion. There's no timetable for his return.
Welker is nothing more than a late-round lottery ticket after he suffered a concussion for the third time in his last 10 games. If this concussion does not end his career, it is possible the next one will.ANALYST: Steve Pimental
Joakim Soria will throw a bullpen session Thursday.
Soria was acquired last season by the Tigers as an insurance policy for the struggling Joe Nathan but he found himself getting injured just six games after being acquired which forced him to miss more than a month. In 13 games with the Tigers last season Soria went 1-1 with a 4.91 ERA after posting a 2.70 ERA with the Rangers prior to the trade. The Tigers expect Nathan to be their closer heading into the season which will mean Soria will once again be in a set up role. Analysis: Jonathan Impemba
