West Indies off-spinners Marlon Samuels and Shane Shillingford have been reported with suspected illegal bowling actions during the second Test against India in Mumbai.
Samuels and Shillingford were reported at the end of the second day's play on Friday by on-field umpires Richard Kettleborough and Nigel Llong, TV umpire Vineet Kulkarni and ICC match referee Andy Pycroft.
Pycroft handed over the copies of the reports to West Indies team manager Richie Richardson after the conclusion of the Test on Saturday.
The umpires' reports have cited concerns over the two bowlers' actions, with particular references to Samuels' "quicker deliveries" and Shillingford's "doosras".
Samuels' and Shillingford's actions will now be analysed independently and if they are found to have bowled with an illegal action during the independent analysis then they will be suspended from bowling in international cricket.
The pair have previously been reported and suspended from bowling in international cricket after their actions were found to be illegal.
They were, however, allowed to resume bowling after they underwent remedial work on their actions and further testing.
Samuels was reported in February 2008 and resumed bowling in international cricket in September 2011, while Shillingford was reported in November 2010 and resumed bowling in June 2011.
