(CBS) The Cubs are placing right-hander Kyle Hendricks on the 10-day disabled list with right hand tendinitis, they announced Thursday afternoon.

The Cubs expect Hendricks’ stint on the DL to take the minimum time, with president of baseball operations Theo Epstein projecting that he misses one start and returns sometime during the road series in Pittsburgh from June 16-18. Hendricks has inflammation on the back of his right middle finger.

“The area is inflamed, and we need to give it some time to calm down,” general manager Jed Hoyer said on the Bernstein and Goff Show on Thursday afternoon.

Left-hander Mike Montgomery will start in place of Hendricks when the Cubs host the Rockies on Friday afternoon. It will be Montgomery’s first start of the season. He made five starts for Chicago last season after being acquired in a July trade.

Hendricks is 4-3 with a 4.09 ERA and 1.20 WHIP this season. In his most recent start, he took a no-decision in a 7-6 win against the Cardinals on Sunday, allowing four runs in four innings.

In Hendricks’ place, the Cubs will call up right-hander Seth Frankoff, 28, from Triple-A Iowa, where he was 1-2 with a 2.77 ERA and 0.94 WHIP.
