The Colorado Rockies placed Canadian left-hander Jeff Francis on the 15-day disabled list with a left groin strain and designated infielder Reid Brignac for assignment Thursday.
The Rockies have yet to announce who will take Francis's spot in the rotation on Sunday against the San Francisco Giants. Colorado may possibly go with righty Tyler Chatwood or lefty Drew Pomeranz, who are both pitching for the triple-A Colorado Springs Sky Sox.
Francis, 32, injured his groin in the second inning of Colorado's win against the Cubs in Chicago on Tuesday. The Vancouver southpaw ended up throwing six solid innings and giving up one run to lower his season earned-run average to 6.00.
Francis also slid awkwardly into second base in the game, tweaking his right knee, but said that wasn't giving him any trouble.
He's not sure how long the groin will sideline him, but it prevented him from throwing a bullpen session on Thursday.
Just when he was finding his form again, too.
"I've been struggling a bit since the first week of the year," said Francis, who has a 2-3 record and 31 strikeouts in eight starts this season. "But to put an outing like that together was very rewarding."
