Guthrie featured twenty-eight times during the curtailed 2019/20 campaign after signing for the Saddlers last July last year, scoring once in the 3-2 comeback victory at the Banks's Stadium against Northampton Town in February.
The former Newcastle United and Liverpool midfielder, who is the latest player to commit his future to the club joining the likes of Sam Perry, Joe Willis, Callum Cockerill-Mollett and Tom Leak in remaining at the club, is eager to get going for the upcoming season.
Speaking via the club's official website, Danny said; "I am pleased to get the deal done. I always wanted to stay at Walsall.
"I have built up a good relationship with the players, the staff and the manager was great to me last year so I was keen to re-sign.
"It’s been a long time but we’re close to coming back to training so I’m looking forward to getting back amongst the lads and get going again."
