Player-coach Brown believes new boy Jackson will improve Scarborough Athletic
Jackson put pen to paper before Boro's 3-1 pre-season victory at Garforth Town on Tuesday night, playing the first 45 minutes of the encounter.
Brown said: "Ash will be a good addition to the squad.
"He fit in superbly on Tuesday night, both on and off the field, it looks like he'll be a good lad to have among the group.

"He's a fit, athletic player who can get up and down the left-wing from the wing-back or full-back position and he showed good glimpses of what he can do on Tuesday night.
"To say he hadn't been to a training session due to Boston being in the National League North play-offs, he slotted in nicely."
