Walton missed the weekend defeat at Doncaster due to a back/hamstring problem and may undergo a late fitness test.
But manager John Hughes has no other new injury or suspension problems and if Walton fails to make it Andy Monkhouse will continue.
Defender Evan Horwood overcame a calf strain sustained last week to play the full 90 minutes at the weekend and is expected to resume in the starting line-up.
Striker Steve Howard is pushing for a recall to the starting line-up. He headed against the post after stepping off the substitutes' bench in the second half at Doncaster.
Midfielder Antony Sweeney (knee) is still not ready and teenage defender Jordan Richards (knee) is out for the season as Pools chase their sixth win in nine league matches.
