The Bucks are set to head to The ARMCO Arena, Damson Park, on Saturday for a 3pm kick-off but the knockout clash could be in doubt due to the big freeze that has hit the United Kingdom.
Forecasts are, however, set to improve into the weekend and it is thought the tie would have more chance of taking place 24 hours later, on Sunday.
Telford and their National League hosts are understood to be in discussion with each other, as well as the FA, about delaying the tie and it is believed there is a good chance of that outcome at 3pm Sunday.
The weather prediction in Solihull is substantially improved on Sunday from 24 hours earlier.
Kevin Wilkin's team are keen to return to action following two postponements due to the freeze – away to Chorley last weekend and at home to Kettering on Tuesday.
They have been forced to train remotely during the last couple of sessions because abject conditions have led to frozen surfaces. The players have been trusted to carry out individual cardio sessions as well as Zoom classes with fitness staff.
But Wilkin and Telford hope the boss will have the chance to reunite with his squad tonight (Thursday) on an artificial surface in the town, should conditions hold up.
