Johnny Manziel remained a spectator in the Hamilton Tiger-Cats' season opener against the Calgary Stampeders on Saturday.
Manziel looked on as starter Jeremiah Masoli threw for 344 yards with a passing and rushing touchdown in the Tiger-Cats' 28-14 loss to the Stampeders.
The 2012 Heisman Trophy winner, Manziel is attempting a comeback with the Canadian Football League team after being released by the Cleveland Browns in March 2016. He completed 21-of-32 passes for 168 yards and a touchdown in a pair of exhibition games.
Masoli completed 25-of-36 passes in the season opener for Hamilton, which travels to Edmonton on Friday.
Manziel signed a two-year contract with Hamilton last month when no NFL team showed interest in signing him after his abbreviated two-week stint in the Spring League.
The No. 22 overall pick of the Browns in the 2014 NFL Draft, Manziel played in 15 games with Cleveland over two seasons. He completed 57 percent of his passes with seven touchdowns, seven interceptions and seven fumbles.
Significant problems off the field led to Manziel's fall. The 25-year-old was investigated by Dallas police in 2016 for domestic violence against an ex-girlfriend, but the charges were dropped when he agreed to undergo counseling.
Following the 2015 season, Manziel entered a rehabilitation center and was suspended for the first four games of the 2016 season for violating the NFL's substance abuse policy.
