South African striker Pieter Malan is to undergo a knee scan after limping after Middlesex’s defeat at Surrey.
The 33-year-old was forced off the pitch in the hosts’ first leg.
As a result, Malan had to beat to seven in the second set of his team’s nine-wicket defeat.
“You have to wait for the swelling to go down to have the best chance of seeing the footage and making sure everything is seen and understood there,” said Middlesex captain Toby Roland-Jones.
“We’re all keeping our fingers crossed for him. Hopefully it’s nothing too serious and we can assess this over the next few days and see how he’s doing.”
malan, who signed for the whole summer with Middlesexrecorded his second half of the season in the first innings of the game at The Kia Oval, as he reached 66 in a 152 second-wicket partnership with Sam Robson.
The right-hander made three appearances for the Proteas Test squad, scoring 84 on his Cape Town debut in the second Test of the series 3-1 defeat against England in 2020.
Malan, who captained South Africa A in three games against India in 2021, missed four months of the last South African season for Boland with a hip injury.
Middlesex have won two and lost three of their first five games, having been promoted last season, and entertain the side two places and four points behind them Somerset on May 18 at Lord’s.
The Taunton-based county are one place outside the Division One relegation zone and are still in search of their first win of the season.
