With a handful of open roster spots remaining after adding 13 undrafted free agents on Monday, the Detroit Lions signed two more players on Tuesday, long snapper Scott Daly and guard Evan Heim.
Neither player has previously appeared in an NFL regular-season game.
Daly, undrafted out of Notre Dame in 2017, had a short, offseason stint with the Dallas Cowboys in 2018. From there, he joined the San Antonio Commanders of the AAF and was most recently with the New York Guardians of the XFL.

Daly will serve as longshot competition for veteran Don Muhlbach, who is entering his 18th season with the franchise after signing a new one-year contract this offseason.
