Smith's knee is believed to be "fine", but he'll still undergo an MRI on Monday as a precaution, NFL.com's Ian Rapoport reports.
Smith was kept out of Sunday's game after twisting his knee while getting tackled during the second quarter. While the extent of his problem is unclear at the moment, Smith's knee injury evidently isn't thought to be serious. Monday's MRI should help clarify his situation, at which point his outlook for upcoming action should be sorted out as well.
