Cade Horton Injury: Throwing off mound this week

Horton (rib) is scheduled to throw off a mound this week, Patrick Mooney of The Athletic reports.

How Horton fares during the mound session will give the Cubs a better idea as to whether the rookie right-hander has a chance to be on the NLCS roster, should his team advance past the Brewers in the NLDS. Horton suffered a right rib fracture during his final start of the regular season Sept. 23 and hasn't pitched since.
