Olsen was placed on injured reserve a few weeks into the regular season with a broken foot.
Olsen was considering holding out in order to secure a contract that would pay him among the top tight ends in the NFL, but he decided against skipping training camp and elected to report to the team.
The Panthers later agreed to include an additional $2 million in incentives to his contract for the 2017 season.
Olsen, 32, is entering the third year of a four-year, $27.75 million contract and is set to make a base salary of $6.5 million over the course of the final two years of his deal.
In 2017, Olsen has appeared in two games for the Panthers and caught three passes for 28 yards receiving and no touchdowns.
Samuel, 21, was taken with the No. 40 overall pick by the Panthers in this year’s NFL draft. Samuel signed a four-year contract worth $6,453,660 that includes a signing bonus of $2,833,572 and stands to make base salaries of $465,000 and $758,348 over the first two years of the agreement.
In 2017, Samuel has appeared in nine games and caught 15 passes for 115 yards receiving to go along with 64 yards rushing on four carries and no touchdowns. He also contributed 221 kick return yards.
