PHILADELPHIA (AP) — Backup quarterbacks Marcus Mariota of Philadelphia passed for 85 yards and Dorian Thompson-Robinson of Cleveland threw for 164 while starters Jalen Hurts and Deshaun Watson watched from the sidelines as the Eagles and Browns played to an 18-18 tie on Thursday night in a preseason game that was marred by injuries. Mariota completed 9 of 17 passes with an interception and was sacked three times in the first half for the defending NFC champion Eagles. Signed to a one-year deal in the offseason to back up Hurts, Mariota was high and off target on several throws while playing behind Philadelphia’s backup offensive linemen and reserve receivers. Most of his completions were short passes that went for longer yards on runs after the catch. Thompson-Robinson was 13 for 25 in the first half.
