It looks like the Seahawks just lost three players for the season.

In addition to Earl Thomas and Will Dissly, who both were put on IR on Tuesday, Mychal Kendricks looks unlikely to play the rest of the way — he was suspended indefinitely by the NFL for his inside-trading case and is likely out of commission until after he finishes his prison sentence.

Kendricks is scheduled to be sentenced Jan. 24 and is facing up to three years in prison. Some recent cases of insider trading have resulted in terms of 15 months, but the money involved was much less than the $1.2 million Kendricks netted from his deals. He probably will get closer to the standard minimum of 30 months.

That would give him a shot at resuming his career around August 2021, when he would be almost 31. Few teams likely would be interested in a guy who missed two and a half seasons; but, if the Hawks were still run by John Schneider and Pete Carroll at that time, they might be open to bringing him back. And he surely would strongly consider Seattle, the one team that offered him a shot after he pleaded guilty.

If he were to get just 15 months, he could be back by May 2020, when he would be just 29 and an even better signing. Kendricks played well for the Seahawks, tallying 13 tackles and two sacks in three games.

The NFL seems to be treating this somewhat like Michael Vick’s dogfighting case a decade ago. Vick was suspended in August 2007, imprisoned in November 2007, out of prison in May 2009 and reinstated in July 2009, after which he signed with Eagles at age 29.

With Kendricks now suspended and K.J. Wright appearing unlikely to return until after Seattle’s Week 7 bye, Austin Calitro seems likely to start at weakside linebacker for the next two games, against the Rams this week and in London against the Raiders next week.

Meanwhile, it looks like the Seahawks might bring back Maurice Alexander to take Thomas’ roster spot (with Tedric Thompson the obvious choice to start). The Seahawks also apparently might have signed former Colts second-round safety T.J. Green.

At tight end, Darrell Daniels seems likely to take Dissly’s spot. And Ed Dickson is chomping at the bit to return Oct. 28.

Despite the three personnel losses, Carroll was optimistic Monday as he expects Chris Carson, Ethan Pocic and Dion Jordan to return this week for the Rams.

“We really feel like we have a chance,” the coach said. “I know we had a couple losses, but we have four guys coming back in and Doug improving, and we’ve solidified the depth at the running back spot. You can see it, and so we have some positive things to look forward to.”
