"It was just something felt we needed to do," Vikings coach Mike Zimmer said Wednesday on the kicking change.
Walsh has missed an NFL-high four extra points this year along with four field goals. His troubles began last season, of course, when the kicker botched a 27-yard field goal attempt with 22 seconds left to hand the Seattle Seahawks a 10-9 win in the NFC wild-card round.
That nationally televised error came in sub-zero weather that marked the third-coldest game in NFL history. Walsh struggled to warm up since -- troubles that ultimately cost him a job.
