Midfielder Bostwick had been used as a central defender in the two games prior to his one-match suspension last weekend but with Gaby Zakuani primed for a recall to the starting line-up, it remains to be seen whether manager Darren Ferguson will continue down that road.
Fans' favourite Zakuani is expected to make his long-awaited return to the team on Saturday.
The Congolese has been absent from the starting XI for the last 13 npower Championship fixtures after he was dropped following the 2-0 home defeat by Wolves on September 22.
But back-to-back 4-1 home defeats could persuade Ferguson to end the centre-back's exile for the visit of high-flying Boro.
"Gaby is always in my thoughts, but other players have done very well in his position since he was left out," said Ferguson.
"There have been signs of mental tiredness in recent games though so I may have to shake up the starting line-up."
With Tyrone Barnett and Emile Sinclair on the transfer list and currently out on loan at Ipswich and Barnsley respectively, Saido Berahino's return to West Brom leaves Ferguson short of striking options.
The teenager has gone back to his parent club after scans revealed he has a chipped bone in his knee which is expected to keep him out for at least two months.
