Essendon tackling machine Devon Smith has issued a warning to rivals: Good luck bringing down Jake Stringer this season.

Fresh off a club best and fairest and league-record 186 tackles in a single home-and-away season, Smith has revealed his struggles in contending with Stringer this pre-season.

While Smith has enjoyed a slow build working through long-term knee issues, Stringer has turned heads at training this summer, bagging seven goals in the Bombers' intraclub last week.

On a String

"Yeah (he kicked seven), and probably passed off about five," Smith told SEN.

"He's like tackling a big fridge at the moment. 

"I don't know if you've ever seen Jaques Kallis, the (South African) ex-cricketer. I saw him at the Giants one day and that's what Jake reminds me of, just a big, powerful person. 

"He's (Stringer) actually done the most minutes out of everyone this pre-season, hasn't missed a session.

"That's pretty good for the guy last year that got to the club that wasn't running too freely."

Stringer will be monitored in the lead-up to Thursday night's opening to the JLT Community Series after leaving the track with a groin complaint on Monday. 

Smith will take the field on restricted minutes, joining Zach Merrett (ankle), Dyson Heppell (hamstring tendinitis) and Joe Daniher (groin) in overcoming delayed pre-seasons.
