Walsall handed Ellis Harrison boost ahead of Grimsby

Harrison was forced to sit out the 1-1 draw against bottom-place Carlisle United at Brunton Park on Tuesday night due to illness. 

37-year-old Albert Adomah was given the nod in attack in his absence, starting alongside fellow veteran Jamille Matt in Cumbria.

But Sadler has revealed that MK Dons loanee Harrison has returned to training and will be in contention on the weekend. 

"Ellis trained today (on Thursday) and is better from his illness," Walsall boss Sadler confirmed.

"He did everything today so he'll be absolutely fine and available for selection."

The 31-year-old arrived on loan until the end of the season from Stadium MK in the final hour of transfer deadline day last month. 

Harrison has made a good start to life at Bescot, registering two goals and one assist in six appearances so far. 

The former Ipswich Town and Portsmouth striker got off the mark with a back post header in a 3-1 win over Chesterfield, and scored inside the first minute in the 2-2 draw at Cheltenham Town last week.

Walsall have collected just two wins from their last 10 games (drawing four, losing four) in League Two and have seen their seemingly unassailable 12-point lead at the top cut down to just two. 

They have gained an extra point over fourth spot, with Walsall sitting 10 points clear of Notts County as it stands.
