Crewe Alexandra duo Daniel Powell & Harry Pickering are being assessed by the Clubs medical staff ahead of this weekend's trip to Newport County AFC.
Powell has been suffering with a viral illness for the last ten days & battled through admirably against Walsall & Crawley but still hasn't been able to fully shake off the problem.
Pickering was forced off at Crawley on Tuesday late on after picking up a hip problem & it remains to be seen whether he'll be fit enough to make the trip to South Wales.
Boss David Artell said: "Daniel has been ill & missed Middlesbrough & because it's a viral thing it doesn't go away straight away.
"I have to say he's been coping admirably, but every now & again it takes the wind out of his sails but we don't anticipate any problems there.
"On Harry, it's good news. He took a bang on his hip which was painful for him, but there's no major damage that's for sure. He's had a scan & that's come back all-clear, so we've dodged a bit of a bullet there."
