Exclusive rights contracts are one-year contracts worth the minimum salary based on the number of years a player has accrued.
Kumerow, 28, originally signed on with the Bengals as an undrafted free agent out of Wisconsin-Whitewater back in 2015. He was on and off the team’s practice squad during his rookie season but returned to the Bengals on a futures contract.
Kumerow eventually joined the Packers and returned to Green Bay on a futures contract for the 2018 season. He returned to Green Bay last year on an exclusive rights contract.
In 2019, Kumerow appeared in 14 games for the Packers and caught 12 passes for 219 yards receiving and one touchdown.
Lancaster, 25, wound up going undrafted out of Northwestern back in 2018. He later agreed to a three-year, $1.71 million contract with the Packers, but was waived coming out of the preseason and later re-signed to their practice squad.
The Packers promoted Lancaster midseason and returned to Green Bay last year on an exclusive rights deal.
In 2019, Lancaster appeared in all 16 games for the Packers and recorded 30 tackles, 1.5 sacks, a forced fumble and a recovery.
