Eagles tackle Lane Johnson was suspended by the NFL pending an appeal, league sources said.

The appeal hearing is scheduled for Oct. 4 and shortly thereafter a neutral arbitrator will render a decision. Johnson will play on Sunday against the Steelers. The Eagles have a bye the following week.

If the arbitrator upholds the suspension, Johnson will be suspended for the next ten games, starting with the Lions game on Oct. 9. He would be eligible to return to the team on Dec. 12 and play in the final three games of the regular season.

A NFL spokesman said the league office had no comment.

"Until I hear from the league office Lane's my starting right tackle," Eagles coach Doug Pederson said during his Tuesday news conference.

Johnson failed a drug test for a banned substance. It would be his second offense. He was suspended for four games in 2014.

Johnson was first told of the failed test in late July near the start of training camp. But he continued to play and started in the first two games of the season as he awaited the results of the B sample. He learned before last night's 29-14 victory over the Bears that the B sample confirmed the A sample.
