The Detroit Lions signed journeyman backup quarterback Nate Sudfeld to be their No. 2 behind Jared Goff.
After cutting Tim Boyle on Tuesday, David Blough was released on Wednesday.
A former San Francisco 49ers backup, Sudfeld, 28, appeared in four games for the Philadelphia Eagles (2017-18, 2020) and was released by the 49ers on Tuesday.
He completed 25 of 37 passes for 188 yards with one touchdown and one interception.
Lions coach Dan Campbell said he got "clarity" on the team's signal-caller situation during a 19-9 preseason loss to the Pittsburgh Steelers on Sunday. Blough and Boyle were a combined 22 of 47 for 201 yards with one TD and one pick.
