Cleveland Browns general manager Tom Heckert is recovering from recent heart surgery, team president Mike Holmgren told Cleveland reporters Monday.
Holmgren stressed that Heckert "will be an integral part of the draft process" and would return to the Browns facility on Tuesday with a slowly increased workload.
Heckert, 44, didn't have a heart attack, according to Holmgren. After not feeling well, Heckert went in for a checkup, which revealed a blockage. The Plain Dealer of Cleveland is reporting the surgery could have been a bypass.
Heckert missed two of the biggest pre-draft events, the Senior Bowl and the NFL scouting combine, and a team spokesman explained his absence as "an illness." He participated in player interviews at the combine via Skype.
This is Heckert's third offseason with the Browns. He had previously served in the Philadelphia Eagles' front office from 2001 to 2009.
