Webb (knee) is slated to make a rehab start at Triple-A Sacramento on Friday and expects to return from the 15-day injured list next week, Shayna Rubin of the San Francisco Chronicle reports.
Webb has been on the shelf since May 9 due to right knee bursitis, but after checking out fine following a bullpen session Tuesday, he's ready to test himself in a game setting. A Friday rehab start would position the right-hander to rejoin the big-league rotation as soon as next Wednesday versus the Diamondbacks in San Francisco. Once Webb is back in the fold, the Giants will have to decide whether to move forward with a six-man rotation, demote Trevor McDonald to Triple-A Sacramento or move one of Tyler Mahle or Adrian Houser to the bullpen.
