Leeds United and Birmingham City had Liam Lindsay watched this week ahead of possible moves for the Partick Thistle defender, according to the Daily Record.
Though Lindsay was forced off at half-time of Wednesday's 2-0 win against Dundee, Leeds appear to have seen enough, with the report stating that the Whites believe he "could be an asset in their bid for promotion from the Championship this season".
Leeds head coach Garry Monk admitted this week that he is looking to add another centre-back to his ranks, with Kyle Bartley's injury leaving only Pontus Jansson and Liam Cooper available for Thursday's draw against Aston Villa.

Birmingham are also looking to invest during the January transfer window, however, and it is claimed that the Blues "could join a January bidding war among other English Championship clubs".
Jags academy product Lindsay has impressed at both ends this season, scoring six goals in 24 league and cup appearances, and his employers are said to be seeking a "sizeable transfer fee" having recently handed the 21-year-old a new contract until 2019.

Leeds and Birmingham were also linked with moves for Wycombe Wanderers defender Aaron Pierre by the Sunday People in September.
