Caulker loaned to Liverpool by QPR

"Liverpool Football Club have completed the signing of Steven Caulker on loan from Queens Park Rangers until the end of the season," Liverpool announced on their website.

Caulker could make his debut in Wednesday's home game against league leaders Arsenal. The 24-year-old, capped once by England, was expected to train with Liverpool for the first time on Tuesday.

Liverpool manager Jurgen Klopp moved to bring Caulker in after hamstring injuries to Martin Skrtel and Dejan Lovren left him short in central defence.

However, Kolo Toure and Mamadou Sakho have recovered from cramp and knee problems respectively, so Caulker may be on the bench against Arsenal.

Formerly with Tottenham Hotspur, Caulker had been on loan at Southampton and appeared in the south coast club's crushing 6-1 defeat at Liverpool's hands in last month's League Cup quarter-finals.
