Seibert signed a contract with the Commanders on Tuesday, Zach Selby of the team's official site reports.
Seibert will take over as Washington's new kicker beginning with Sunday's game versus the Giants in the wake of the Commanders cutting Cade York, who missed 47- and 56-yard field goal attempts in the team's Week 1 loss to the Buccaneers. Since entering the NFL in 2019, Seibert has bounced around between five organizations and has appeared in 31 career games while converting 45 of 56 field-goal attempts (80.4 percent) and 56 of 62 extra-point tries (90.3 percent).
