Despite the Atlanta Falcons’ win to claim the final NFC playoff spot, the Seattle Seahawks had a chance to finish the regular season 10-6 in front of the home crowd at CenturyLink Field . . . and kicker Blair Walsh had a shot to seal the deal.

With his team trailing the Cardinals 26-24 and 37 seconds left in the fourth quarter, Walsh’s 48-yard field goal attempt sailed wide right along with the Seahawks’ hopes for a playoff appearance.

During the television broadcast, coach Pete Carroll could be seen mouthing the word “unbelievable.”

“First thing I thought of is that I felt so bad for him because he’s trying to get out of this thing and he just didn’t get to put it to rest today,” Carroll said during his postgame press conference. “He battles and competes his tail off to do well, and he wants to do great for everybody and all that.”

The Seahawks signed Walsh, a former Viking, to the roster in February in anticipation of losing longtime kicker Stephen Hauschka, who ultimately left for the Bills at the start of free agency.

Walsh made 21 of 29 field goals attempted on the season, with a long of 49 yards, for a success rate of 72.4 percent. But with Walsh likely out the door as a free agent this season, he’ll be most remembered for his misses.

Walsh botched all three of his field goal tries in the first half of Seattle’s Week 9 loss to the Redskins, although Sunday night’s miss might be the most painful, as his last.

“There’s a kick and if you make it, maybe you leave the rest of the stuff behind, and he didn’t get to do that today,” Carroll continued after the game. “He’s a good competitor, and it breaks my heart that he wasn’t able to get that done.”

It sounds like Walsh might have run out of attempts in Seattle.
