The Raiders are expected to place O'Connell on IR due to a fractured thumb sustained during Sunday's 20-15 loss to the Rams, Ian Rapoport of NFL Network reports.
O'Connell could be sidelined up to six weeks, a development which puts Gardner Minshew back under center for Las Vegas. In his lone full start this season, O'Connell completed 27 of 40 pass attempts for 227 yards, one touchdown and one interception in Week 6 versus the Steelers. Across four appearances on the whole, O'Connell has thrown for 455 yards, two touchdowns and two INTs. Adam Schefter of ESPN reports that O'Connell will seek a second opinion Monday to confirm the severity of his injury.
